Sketmatik: Extrusion of medical spiral breathing tubes

964

A recent development of Sketmatik is the KEP 38-25-S line for the production of spiral breathing tubes. These tubes are made of PVC-soft for the hoses on which a PVC-hard spiral is applied during the production. The extruders are particularly used for the manufacturing of medical catheters with a diameter of 15 to 19mm. The line consists of the extruders KEP 38-25-S (PVC-soft) and KEP 30-25-S (PVC-hard), co-extrusion dies, calibrator, dual cooling (with adjustable inflow channel), automatic cutter and hose store. By the supplier’s own account, haul-off speeds of more than 4m/min were achieved.
